Hello all, Was wondering if someone might be able to explain why it is that we often see total CPU Utilization (User + System + WIO + Idle) at values substantially below 100%. When this happens, the reported user portion is almost always zero while running top on the box shows that 90+% of the CPU(s) is(are) being utilized by user processes. The XML stream on the gmond collector (we are using gmond in unicast mode) node is reporting the values that appear recorded in the gmetad's RRDs. From this, it appears that the CPU User metric isn't registering the utilization properly.
Linux kernel versions are 2.4.x and 2.6.x on Red Hat and SLES x86 boxes. Sample data collected from RRD's to follow sig in which the reported total sum of CPU Utilization was below 10%.
